Acoustic panel DETA

T3 can be used where high absorption is necessary. The panel in this form is effective for controlling réverbération and echo formation inside rooms designed for speech related activities due to higher absorption performance at mid-to-high frequencies. T4 is suited where absorption is necessary on wall surfaces and to tune optimum réverbération desired for a room. T6 can be used where medium absorption is demanded for low frequency range, especially suited for electroacoustic sound reinforcement with music material of dominant low-frequency energy content in such rooms. Besides absorption, ail configurations can provide effective sound scattering for the range of frequencies from 250 Hz to 2000 Hz due to variations in both depth and length of each element within the modules. This allows even distribution of sound within the room and prevents disturbance from acoustical defects such as harsh sound reflections, acoustical glare, echo or flutter echo.
